T0 all whom zt may concern:

Be it known hai; I, JOSEPH HIRN, a citizen 0f the United Stabes,residing ab Ohillicothe, in the connty 0f Boss and State of Ohio, haveinvented a new and usefu1 Improvement; in Oar-Conplings, 0f which Ehefollowing is a specification, reference being had to the aecompanyingdrawings.

My invention re1ates to ear-couplings, the object being 130 provide apivoted laiach for snpporting the 1ink in a raised position and adapted130 be struck by the 1ink of the adj2v cent car t0 release the pin andeffeet a compfing.

A further objectof the invennion is t0 improwa the details 0fconsbrucbion, and 130 pro vide a coupling which sha1l be positive andeffeetive in its operat-i0n, and one t hat Will not be likely t0 geb01113 of order.

W'it-h these ends in view the invention nonsists in the improvedconstruction and combinations 0f parts hereinafter fully described, andpointed ont in Ehe claim.

In the dmwings, Figure 1 is a front elevation ofaear-couplingconstructed in accordance with my invention. Fig. 2 is a sectionelevation showing the pin supported in a raised position, and Fig. 3 isasection 0f a modification.

In the accompanying drawings, in whieh ]ike 1esters of referenceindicate corresponding parts in all the figures, A represents thedmw-head, which is provided with the usua1 linkopening, a, andpin-openings b, t0 receive the coupling pin B. The rear end 0f theopening, a in the draw-head is provided witsh a seat, (l, in which theend cf bhe coupling- 1ink rests when the ears are coupled.

C- represents an opening forme. in 1bbe upper inner side 0f ohedraw-head just; in rear of the upper opening, b, and havingcommunication with said opening andwibh bhe 1inbopening, as shown ab e.

111 the opening0is located a1atch, Dwhich is substantially segmental inform. 'Ihe head 0f this latch is slightly 1arger than the lower end ofthe opening G, so that when said 1atch drops 120 support bhe eouplingpin1'ts end projecs beyond the opening in the lower end of said opening O,anti extends under the pinopening b, 'uhus supporting the pin. When l:helatch D is larger ab its npper end than the opening C a5 its lower end,the said latch is inbrodnced into the opening by providing an openingupon the upper side 0f Lhe drawhead, Which may after the latch is inposition in opening O, be closed, 130 prevent the latch from jumping0ut-.

In the modifieation shown in Fig. 3 the latch is provided with anelongabed slot izhrough which passes a rod, f, thus pivobing said 1atchin Ehe opening C, and allowing a limited veriea] movement.

In the operation 0f my invention the lower end 0f Ehe pin rests uponltheupper side of the Iower end of the cupling-latch. VVhen the cars cometogether, thelatch is struck by thelink 0f the adjaeent Zcar, thusthrowing it back int0 the opening C und releasing Lhe pin, thuseffecting a, coupling.

Having fully described my invention, what I claim as new, and desire t0seeure by Letters Patent, is

The combination, with a draw-head having t1he usua1 link andpinopenings,and the opening C, smaller ab its lower than ab its upper endund located in theupper inner side 0f thedrawhoad, of alat.ch located insaid opening, said la tch being slightly curved and larger'ab its upperthan ab its Iower end and located in the opening O, and adapted t0supporb th e complingpin upon its 10wer end, substantially as set forth.

In testimony that I c1aim the foregoing as my OW11 I have hereto afi1xedmy signabure in presence 0f bwo witnesses.
